<p>Apparatus (10) for supporting and determining the orientation of an adjustable rearview mirror (716) relative to a determined coordinate system includes a first support member (12) rigidly connectable to a motor vehicle, a second support member (14) movably connected to the first support member (12), moveable about a first axis (X) and about a second axis (Y) intersecting with and perpendicular to the first axis (X), a mirror housing (717), first and second sensors (18, 20), and a signal processor (22). The first sensor (18) senses the movement of the mirror (716) about the first axis (X) and generates first sensor signals correlatable therewith. The second sensor (20) senses the movement of the mirror (716) about the second axis (Y) and generates second sensor signals correlatable therewith. The sensors (18, 20) are preferably positioned to be substantially decoupled from one another in the sense that the measurement of the movement of the mirror (716) relative to one axis by one sensor (18) is independent or approximately independent from the measurement of the movement of the miror relative to the other axis by the other sensor (20). The processor (22) is electrically connected to the first and second sensors (18, 20) and calculates the orientation of the mirror (716) relative to both the first and second axes (X, Y) based upon the sensor signals and mirror geometry parameters.</p> |
